fuses

What is the single fuse that sits underneath the fuse block and starter relay, what is it for it keeps shorting and now my two wires have melted . If you can answer half the question that will be ok . I plan to run the red wir to a major positive line and the black wire to a major black cagulation of ground wires hopfully it won't continue to short. Also what would make the ignition coils send spark sometimes and other times no spark whatsoever. I here a small light click evertime like a solenoid making contact and then the ignition coils start sending spark but i can't find a solenoid it sound like it comes from the left side it's a light tick and then spark.

Accesory Fuse

If you're talking about the horizontal fuse at the bottom of the panel, that's an accessory fuse, typically not used unless you connect a radio or some other "non-standard" item to it. You may want to find out what is at the other end of the wires and if not essential, disconnect it.

It sounds like you've got someting wired in in the accessory circuit, but it is causing a short somewhere. This falls under the category of electrical gremlins. You'll want to follow Cobia's suggestion to find out what that is wired up to that fuse, determine if you want/need to keep it, and look for the short that is eating fuses.

Don't do that.
Well, you can but you won't be able to replace fuses fast enough. It will be a dead short. The black should go to aux lights or something.
